1862-1943 German Mathematician
He critically examined the foundations of geometry. He made important contributions to the theory of numbers, the theory of invariants and algebraic geometry, and the application of integral equations to physical problems. At the International Congress of Mathematicians in 1900 he listed 23 problems which he regarded as important for contemporary mathematics; the solutions of many of these have led to interesting advances, while others are still unsolved.
